Subject: 24.4; Invalid face: linum
--text follows this line--

I'm using linum-mode. At various points (e.g., after M-x speedbar), I
see "Invalid face: linum". (And the speedbar doesn't come up.)

*Messages* shows "nlinum--face-width: Invalid face: linum".

I can't reproduce this and have no idea how this could happen.
Can you give a minimal example starting from emacs -Q?
The linum face is defined in linum, which is required by nlinum, and
according to your report is loaded:

‘nlinum-mode’ I suppose.

This issue has been reported and discussed here

https://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00022.html

and was hopefully fixed for Emacs 25.1.  I have no good idea how to
handle this for your version.

I know it's unsatisfactory.  Is there a way to find out whether a face
has been loaded?  Then we could check that in (n)linum-mode.

Does 'facep' fit the bill?

Then ‘nlinum-mode’ should probably use ‘facep’ in ‘nlinum--face-height’
and ‘nlinum--face-width’ to check whether FACE is valid.

BTW is there any reason why ‘face-font’ calls lookup_named_face with the
third argument true?  If FACE is unspcecified, ‘face-font’ is supposed
to return nil anyway.

This was fixed in 25.1, so I'm closing this now.
